The midterm election ends - and a new controversy begins in the nation's capitol.

On Wednesday, Attorney General Jeff Sessions stepped down after President Trump asked him to resign.

President Trump thanked Sessions for his service in a tweet, and announced Matthew G. Whitaker is taking over as acting attorney general.

Tennessee lawmakers are some of many reacting to the news.

A statement from Tennessee Sen. Lamar Alexander (R) says in part:

"The one thing this does make certain is that the Mueller investigation into Russian meddling in elections will continue to its end, as it should, because no new Attorney General can be confirmed who will stop that investigation."

The president has said several times in the past that he was disappointed in Sessions, specifically about Sessions' recusing himself from overseeing the investigation into Russia meddling.
